FLOATING DUMPlNG-DOCK.

SPECIFICATION forming part of Letters Patent No. 232,316, dated September 14, 1880. Application filed April 3, 1880. (N0 model.)

To all whom it may concern:

Be it known that I, WILLIAM D. TRACY, of the city, eounty,.and State of New York, have invented a new and Improved Floating Dumpiug-I)ock, of which the following is a specification.

The object of this invention is to provide a floating removable dock that may easily be moved in the water from one bulkhead to another, and connected therewith, and from which garbage, earth, and other matter can be conveniently dumped without creating offense.

My invention relates to an improved floating dock upon which garbage, street-sweeping, and other carts may be driven from a fixed dock or wharf, said floating dock being provided with a projecting or overhanging platform, from which the contents of such carts may be safely and conveniently dumped directly into scows or other vessels moored alongside the said floating dock and directly beneath its overhanging portion; and it consists of adjustableaprons or screens suspended from the front and ends of the overhanging portion of the floating dock to inclose the scow receiving the garbage, &c., and to prevent the dust or odor from the dumped material from escaping.

Figure 1 is a side elevation of the device. Fig. 2 is a plan of the same.

Similar letters of reference indicate corresponding parts.

The construction and arrangement of parts are as follows: In the drawings, A represents the scow portion of the dumping-dock; B, the deck, supported by the posts 0, girders D, and braces F; and F are the two gangways, secured to the deck portion of the dock by hooks a, that engage in the eyebolts Z), that are securely held by nuts.

G are the raised side strips or timbers of the gangways, with ends projecting upon the deck to give additional strength and stability to the said gangways, and these strips are firmly bolted to the transverse planks H, that are themselves bolted to the timbers I below them. ff indicate the holes for attachment of mooring chains or ropes.

The deck B is extended laterally several feet beyond the outer side of the scow proper, so as to reach entirely over a scow that may be beneath said deck B to receive the dumped material, and about midway of its extension it is provided with a guard sill, L, designed to block the cart wheels and prevent the carts from backing off the said dock. Outside of the guard-sill L the extension of the deck is provided with one or more dumping-openings, M M, that may be closed by sliding doors N N, that are operated by ropes' and pulleys O O, or other convenient device. Over the ends and front of the said deck B are suspended aprons or screens S S by ropes P, that reeve through pulleys Q, fixed in the tops of the standards R, which are themselves fixed against the guard-sill L. These aprons or screens S S may be raised by means of the ropes P to admit the entrance of a scow beneath the deck B, and then will be lowered to prevent the escape of dust and foul odors from the material dumped through the openings M M. Then these aprons S S will again be raised to permit the dumping-scow to be removed. The scows or other vessels N intended to receive the dumped material are secured while being filled alongside the floating dock and directly beneath such overhanging portion of its deck B, as shown in the drawings. Thus the carts, loaded with garbage or other material to be dumped, having been hauled up one of the gangways F and turned about on the platform B, are run back until the wheels strike the guard-sill L. The bodies of the carts are then tilted and their contents discharged through the openings M M directly into the transporting scows N below. To render the dumping operation still safer I extend a rail, K, along two sides of the deck.

By the above-described construction of floating dock garbage, earth, &c., may be dumped into scows with safety and convenience and without offense.

I do not claim connecting a boat or floating dock with a permanent wharf by means of a hinged bridge or gangway.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- 1. The improved floating dumpingdock formed of the scow A, having the broad flat deck B, provided with openings M M and doors N N, supported upon the timbers O D,

and projected laterally beyond the outer side of the scow,' as shown, and provided at its ends and front with suspended adjustable aprons or screens S S, that are operated by means of ropes P, passing over pulleys O, fixed in the standards R, the guard-sill L, applied to the center of the said platform and the guard-rail, all arranged as shown and described, for the purpose stated.

2. In a floating dumping-dock, the combi nation, with the deck 13, provided with openings M M and doors N N, of the depending aprons or screens S S, substantially as herein shown and described whereby the escape of dust and odors is prevented, as set forth.
